반응 단계
A mixture of propionic acid (0.89 ml, 12 mmols), 2,3-diamino-4-picoline (1.23 g, 10 mmol) and polyphosphoric acid (40 g) was heated to 100° C. for 6 hours. Work-up of the reaction and purification of the crude product according to the procedure described in Step 1 of Example 9 gave the desired compound (1.46 g, 90%) as a tan colored solid.
